There are several types of catheters that are commonly used in veterinary medicine to help animals recover from injuries, illnesses, and surgeries :
Esophageal Stethoscope: This long flexible tube has a rounded end that is inserted into the esophagus until it rests beneath the heart. It is useful during procedures that require anesthesia.
Endotracheal Tube: This flexible tube is used to establish an open airway to deliver gas anesthesia or oxygen .
Tracheostomy Tube: This short tube is used to establish an airway through the tracheal wall in a patient that has an upper airway obstruction or is critically ill .
Indwelling Intravenous Catheter: This flexible catheter is placed over a needle or through a needle. The needle is used to puncture the skin and vessel; the catheter is then threaded into the vein. The catheter has a standard hub that receives the IV drip set or syringe tip. Sizes range from 24-gauge × ¾ inch to 10-gauge × 5¼ inches .
Intravenous Butterfly or Winged Infusion Sets: This catheter has a standard 1-inch needle that is inserted into a vein. The wings are used to secure the catheter in place.
